Taken from XboxFamily.com:
"Sadly, whenever a big story breaks, every scammer on the planet tries to find a new angle. That has happened with the news of Microsoft working on a motion-sensing controller add-on for the Xbox 360. Don't be fooled by fake images.
Below are images of the original motion-sensing prototypes that Gyration had designed for the Wii in 2001. For some reason, misinformed people are posting these images as the "new controller". Considering Gyrations is rumored to be working on an add-on, not a controller, that should be people's first clue. Also considering the images have been around for six years, well that should be another clue.
Images below are from 2001. They are not new."
